When it comes to your audio and video equipment, there are a bunch of intricate parts that work together to make music and movies sound and appear the right way. Something as small as a transistor burning out on the circuit board or a frayed speaker wire can end movie night in a snap.
If the audio goes out in your Pioneer system, there are a few steps you can take to locate the problem to repair it. First, start with the wires in the back. Check the speaker wires for fraying or tears that might sever the connection. Also, check that power cords are plugged in and all audio cables are secured while inspecting them for damage. If the cords are in order, you can next check the speakers by removing the back covers using a screwdriver and examining them for physical damage. You can also rub the leads on a 9-volt battery to listen for a popping noise that indicates they're working. If the speakers are in order, then check the receiver for signs of physical or water damage. You can open up the casing and use a multimeter to test the electronic components.
